Diffuse relaxation approximation in a heated Fermi system
arXiv:2103.17129 · doi:10.1142/S0218301321500609
Abstract
An expression for the two-particle relaxation time of collective excitations on a distorted Fermi surface in the diffusion approach to kinetic theory is obtained. The general case of momentum-dependent diffusion and drift coefficients is considered. The temperature dependence of the obtained expression is established.
